Seurat Aims to Disrupt Metal 3D Printing with 2 Million Lasers

3D printing company Seurat is mentioned after pointillist painter Seurat because, like him, the company wants to work pixel by pixel. Preferably than discover a laser over the whole build, they want to illuminate and heat every pixel of that stratum at once for faster results.

Seurat's yield technology is period Area Printing and uses what it requests Optically Addressed Light Valves( OLAVs )." Every pixel in the OALV characterized its own laser spot, effectively creating a multitude of individual lasers out of one very powerful laser" that assignments" laser light-headed down to a bed of metal pulverization, weld a patterned country in an instant, and build a multi-layer part ." If you positioned it like that, it sounds a hell of a lot more like Mondriaan, right?

By illuminating an part photograph berthed layer at one time, Seurat misses the point that the machines spend 60% of their age recoating, but this is a hugely exciting development none the less. By reducing the examine epoch of the laser, improves is likely to be handled vastly faster, like high speed sintering( HSS) for polymers and other diode and array laser projects underway.

Seurat's approach is a fundamental challenge to the existences of existing powder bunked synthesi( PBF) business. EOS has been working on a similar technology since at least 2013, but no one knows when or if they'll pull it off. Their VCSEL approach could present similar results. If we compare the multi-laser approaches to Seurat's, however, the latter will be significantly cheaper to implement with less complexity and higher speeds.

Seurat now has $ 33 million to implement this technology which doesn't seem much given the challenges in commercializing OALV and information systems itself for metal printing. The busines firstly published metal personas in 2015 and has now just come out of stealth mode. Presumably Desktop Metal's stock moves, the proposed SPAC of Markforged, and the resulting interest in ExOne and voxeljet establishes now a exceedingly opportune period for a metal 3D publishing house to be looking for money.

Its too early to tell if Seurat will be able to commercialize its technology successfully. It is very difficult to go from a technology to a manufacturing machine that works well in an industrial settle. Velo3D has managed to do this but it is far from facile. Co-founder and CEO James DeMuth developed the technology at Lawrence Livermore National Laboratory and worked with Erik Toomre who was at Tesla, Volkswagen and Sun to develop the firm. The Chief Scientific Officer Andy Bayramian wreaked at Lawrence Livermore for over 24 years as a physicist and has coauthored a assortment of newspapers that melt my brain on lasers and much more besides. The VP of Engineering lead four companies to IPO. Partners include Denso, Porsche, GM, and Siemens with Porsche and GM having invested in the house as well. There is a lot of pedigree and hope in this firm.

Their predicts will likewise fundamentally deepen our industry if they can be realized. The company points to" precise laser exertion restrain in time and cavity supports terminated caliber self-control" and" by mellow cleanly, typical character sizing restraints will be overcome ". At the same experience, Suerat asserts that," accuracy and skin-deep finish combine to enable true net-shape processing ." The busines hopes to achieve a lot of substantial sea change-type performance enhancements for information and communication technologies simultaneously. If they do it, we will be a lot closer to 3D etching cost-effective roles for industry and a lot of other companies will be dead in the water. That is a big " if", though.

The technology is actually more of a Seurat-meets-Jackson-Pollock. Sad that they didn't go for JacksonAt or SeurOllock. I'm glad that they didn't pick the other pointillist, Pissarro, since that would be difficult for everyone to incantation and you'd have to explain all the time that,' yes they're bold' but not conquistador-ambitious. Henri Delavallee is probably likewise out, due to spelling as well. Many would google" Del valley" and be brought to an end at a home inspections companionship by mistake.

Although I personally ardour Theo van Rysselberghe, I could imagine that mentioned would also be suboptimal as a catchy startup label. Think of their good receptionist. Toorop sounds very cool, and I can not fathom why they didn't elect that. I'm positively miffed that they didn't select Hippolyte Petitjean who is, although undeservedly, much less known, has one of my favorite epithets ever. I was only able to imagine the disillusionment as this American fellowship was turned down by the still-living American pointillist Chuck Close, who perhaps has the best name in all of painting.

I think Signac would be a delightful alternative, perhaps something to think of if you'd like to compete with Seurat. It would be much nicer to have a bevy of impressionists define our manufacture than the instead macho tech-heavy refers we have now.
